This invention relatesito= dough dividing machines and has special reference tothe provision of an apparatus for collectingy and recovering oil expressed from said dough dills a dough dividing compartment and to then cut such cake or disk into .a multiplicity of equal parts or sections.` To prevent the dough from adhering or sticking to the. Walls of the dough dividing compartment,

E the said Walls arefirst coated With a layer or coatingofbaking oil usually applied With a brush in fair or copious amounts.

In the dough compacting and cutting op-`VV erations, aV substantial part. of the oil used in the coating s tep is expressed or extruded from the machine mixed. with small particles of dough. This mixture drips. from the dough dividing apparatus onto and over the; framevvorkof the machine, part, of the drlpplngsj.

lodging on the framework and parts of the ap-` paratus and other parts of the drippings c ollecting on the floor or other support on which the machine is mounted, With the` resultthat the machine framework as Well as the` Working floor area therefor becomes unsightly and unclean afterl short periods of use of the machine, necessitating repeated and time consuming cleansing operations; Furthermore,

I have found that substantially onehalf of the oil employed is thus extruded or expressed from the machine and is; thereby Wasted.

A prime desideratum of my present invention centersr about the provisionof a dough dividing. machine in which .the oil and-dough' o drippings expressed from the machine inthe operation thereof'are collected and disposed of in a manner to produce aclean and sanitary use of the machine-over extended periods of time, thus obviating the aforementioned dis;

machines. I

A further prime object of my present 1nvention is directed tothe provision of'gap.- paratusrfor dough dividing machines functioning to collect the dripping mixture of advantages incident to the prior use of these@ dough and oil extruded therefrom and to separateandrecover the oil fromfthe Inivxture for further use.` y y Other prime objects of theinventionim" clude the provision of a mechanism 1for sep-- aratingand recovering the oil expressedfrom the` dough dividing machine, `which `mech@` PATENT' OFFICE anism is made in the formof an attachment? 1 Which may he readily dough dividing` machines.

.To the .accomplishment ofthe foregoing and such other objects as Will hereinafter appear, my invention consistsinthe elements and their relation one. to the other, as hereinafter more particularly described ande applied to.V standard being had to the accompanying drawings Y Which show the preferred embodiment ofmy invention, and in which: l

Referring now more in= detail to.. the draw--V ings, having, reference first to- `1 thereof,V the dough dividing machine tovvhichthel` apparatus ofmy invention may be applied com-i (partly shorvvn) 15, the saidzclosure being hingedlynmounted atl 16. Inj Vthe compart e. ment 12 a mass of dough to be subfdivided is placed; and. in the-operation of thef machine the said dough.` mass is first, compacted. into a iiat cake andvthen cut into a. multiplicity of equal parts. This isaccomplished by the up-,i

ward movement first imparted to the sectionalized movable bottom 14 and then by the operation of a plurality of knives, one of which, 17, is shown in the.drawings,`the said.

4, knivesbeing'independently movablein the bottom wall 14.

The operating parts of the dough dividing machine being well known 'and forming no part of my invention, the same are herein.

illustrated merely in a fragmentary. way but sufficient to explain the principles and operation of my present invention.V The weighted door 15 is counter-balanced by a weight 18,

the lower end of which is slidably mounted f' in a sleeve 19 pivoted at 2O to the framework 10 ofthe machine and the upper end of whichk is hinged as at4 21 to an arm 22 formed integral with the closure or door 15. The sections of-'the movable vbottom wall 14 are f` mountedon a plurality of studs or rods 23, 23

drawings with theV door or closure 15 open. l

fixed toa plate 24 which plate is formed integral with a sleeve 25'keyed for limited slidablel movement to a vertical operatingv shaft 26.V The knives 17 are all affixed to a plate 28 which ismovable independently of theV rods 23'. v In operation, the parts are firstcaused to assume the position shown in F ig. 1 of the plate 24 Vand which is guided by the studs or Before placing av mass of dough-in the dough dividing*compartment-12, the walls 13 and 14 thereof are coated or painted with a layer or coating of oil vtaken from an-'oil supply receptacle 29 by meansof a brush 30, the oil supply receptacle being stationed on a drip pan 32 fixed to the framework 10 of the maf chine, vas clearly shown in F ig. 1 of the drawings. The doughinass is then placed in the compartment12 and the door 15 closed and latched.l An operating lever 33 is then depressed for causing the bottom wall 14 and knives 17 to be moved into an elevated position 'for flattening'the dough mass against the covering or door 15, this to effect an even spread or distribution of the mass in the dough compartment 12, after which the knives 17, by-continued movement of the operating lever`33, are given an independent` f upward 'movementeifective for cutting the attened dough mass into a multiplicity of parts. p y

In these doughcompacting vand cutting operations, oil mixed with particles of dough is forced through the passages and crevices existing between the knives 1.7 and the sectionalized bottom wall 14, as well. as between the bottom wall 14 and the surroundingwall 13, and this mixture falls from the machinel Vindrippings illustrated as cl, d in Fig. 1 of the drawings. ,Y y

In accordance with my present invention,

Iprovide means for collecting the dough and` oil mixture which is extruded or expressed from the dough dividing machine in a manner to produce a clean and sanitary use of the machine over extended periods of time and for separating the oil from the particles of dough for the purpose of recovering'said oil for further use. I have found that substantially half of the oil used may be thus recovered or salvaged for re-use. These objects of the invention I accomplish by providing a means generally designated as a arranged below and covering the area of the dough vdividing apparatus and functioning for receiving the drippingsofoiland dough expressed from said apparatus combined with anneans generally'designated as Z) communicating with said separating means a for receiving and collecting the oil separated thereby.

In th'epreferred embodiment of the invention, the apparatus for collecting and recovering the oil is made inthe forinof an f attachment which may be readily applied to the base-of the machine framework 10 and the same comprises la pair of supporting channelfirons 34 and 35, one arranged on eachfy side of -tne machine, which channel irons areA bolted to the legs of the framework 10 by means of the bolts or other securing means 36, 36. The -meansa which receives the oil and doughdrippings, vcomprises an open pan extending Aover an area covering substantially theccinpletemachine so that oil drippings from all sources, including lthe-pan 32 may be collected and recovered. rlhe pan a, wl'iicii is desirably bolted between" the framework 10 vand the channel irons 34 and 35,'is pre-ferably dished and provided centrally with plurality of oriiices 37, 37 which function lo strain the oil and thus separate the same from vthe particles of dough which are retained in the y'pan and'which may be removed there- The means b com! vprises a Acollecting receptacle arranged below from from time to time.

the pan a vand receiving the oil strained therethrough `and desirably this receptacle coinprises a drawer slidably receivable by the T channel irons 34 and 35, the 4said drawer being provided with a vhandle 33'.

For both stationarily and transportably support-ing the machine, I Aprovide a front supporting leg 39 secured at its opposite ends if' to the channel irons 34 and 35 and rear supporting wheels 40`and 41 journalled on an axle 42 which is mounted inthe channel irons 34 and `35A and held against Vtransverse inovement therein by means of spacedvcollars 43,

43. This wheel-and axle structure is -supplied with the standard machine and is usually mounted'at the rear of the framework 10 thereof, the axlebeing coincident with the pivot 2O of the sleeve 19. Inapplying the attachment apparatus of my present invention, the wheel and axle structure is removed from its customary positionand is reinounted in the channel irons 34 and 35,l as described and as bestshown in YFigss--l to 3 of the draw- I l:

ings. lIt will be understood that in moving the apparatus from place to place, a pair of` handles 44 (one offwhich is shown in Fig. 1

of the drawings) is moved from the full to the dotted line position shown in Fig. 1 of the drawings, said handles forming levers for raising the front end of the machine from the foot support 39.

The use and operation of the oil collecting apparatus. of my present invention and the many advantages thereof will in the main be fully apparent from the `above detailed description thereof. It will be apparentthat the combined oil separating and collecting `means forms compositely an attachment which may be readily secured to the bottom of, the framework lO of the dough dividing machine without altering the construction of the machine, other than removing the wheeled support 40 to 42 therefor, which wheeled support is then replaced by being mounted on,

the attached apparatus. lIt will be further evident that the collecting means a is posil tioned to receive the drippings of mixed oil viding apparatus in they operation thereof and dough from all parts of the apparatus.

and to strain the oil from the mixture, which oil drains into the collecting receptacle b. The particles of dough which remain-on the strainer pan a may be scraped therefrom from time to time with ease and convenience. The separated oil collecting in the receptacle t may be removed at will from time to time for re-use. With .the use of apparatus of the invention therefor, I am enabled not only to effect a substantial economy by recovering, the oil otherwise wasted but to eliminate the unsanitary disadvantages incident to the use of these dough dividing machines.

While I have shown and described my invention in the preferred form, it will be apparent that many changes and modifications may be made in the structure `disclosed without departingfrom the spirit of the invention, dened in the following claims.
